Cookiecutter sharks are well known for feeding on large animals, and leaving a cookie-cutter-shaped wound, hence that comically name. These are small and dark sharks, typically found in deep tropical and subtropical waters. Despite their small size, these sharks can pose a significant threat, although rarely. Of the seven reported cookiecutter shark attacks on humans worldwide, six occurred in Hawaiʻi. A new research connect the interactions between cookiecutter sharks (Isistius brasiliensis) and humans, particularly among channel swimmers in Hawaiʻi. The study showed how environmental conditions such are moonless night can increase the likelihood of these attacks.

The nocturnal feeding behavior and zoogeographical habitat of cookiecutter sharks greatly reduces interaction of this species with live humans. However, the growing popularity of channel swimming in Hawaiʻi and swim start times have contributed to an increasing likelihood of live human and cookiecutter shark, according to the researchers, moonless night sky is a significant risk factor for night swimmers.

If you've ever wondered why people in Hawai'i hate tourists, try to wrap your mind around the fact that there are CURRENTLY, RIGHT NOW, tourists sipping martinis and looking at fish within swimming range of the fresh corpses of local people who couldn't escape the overnight destruction of their entire town.
Try to comprehend that there are fully functional, high capacity boats passing through the waters in front of an area full of survivors who are stranded and in need of supplies, refusing to help. They are hosting snorkeling tours.
Really think about, try your best to actually picture over two thousand people unhoused and in need of shelter, with nothing but the clothes on their backs and nothing to return to. Understand that the island, stolen land, is littered with hotels full of air conditioned of rooms with beds and showers and toilets, each fully equipped to host hundreds of families for weeks, turning these people away because they're booked up with tourists who refuse to leave.
And understand that these tourists were offered free transport to return home or be hosted on other islands. Free. Courtesy of local tax dollars. 4,000 wealthy tourists were offered free flights shelter on Oahu and begged to leave the island, BEFORE the survivors were given shelter.
And enough still insisted on remaining and carrying out their vacations that people are left without shelter and resources while they enjoy "their stay in paradise".
[Edit]: This current situation, and this type of tourist behavior is horrifying beyond words. In other circumstances, the tourism situation is much more complicated, and I need to ask that people do not add on to this post unless they are local.
